On order up to 150 business days.

The device is under development, the estimated start of deliveries is the third quarter of 2024.

Wiren Board 8M is a PLC powered by free software.

Wiren Board M series PLC are used in the tasks of monitoring server and climate equipment, dispatching and collecting data from metering devices, as a basis for industrial automation. The metal case with the possibility of grounding protects the controller from electromagnetic interference and mechanical damage.

Different types of mounts allow you to install the device on a DIN rail or in a 19" server rack.


Hardware and software

Any configuration includes an industrial 4-core 64-bit ARM Cortex A53 processor with a frequency of 1.5 GHz, but the available RAM and permanent memory depend on the version:

  • industrial (−25 to +75 °C): up to 4 GB LPDDR4 RAM and up to 64 GB eMMC;
  • extended industrial (−40 to +75 °C): 1 GB LPDDR4 RAM and 8 GB eMMC.

The controller uses the open operating system Debian Linux 11, kernel 6.8, which provides ample opportunities to install third-party software. There is also hardware protected a key store that can be used to authorize the controller in its services or to link software licenses.

The built-in software is free, open and allows you to configure the controller and devices connected to it, write automation scripts, store and view archives measurements.

Interfaces and Communications

In the basic configuration of the controller:

  • 1 × MicroSD slot, up to 60 MB/s
  • 2 × Ethernet 10/100
  • 1 x USB Host
  • Wi-Fi 802.11n (AP, client), two bands 2.4 and 5 GHz
  • Bluetooth 4.2 + BLE
  • 2 × RS-485
  • 2 × 1-Wire/digital inputs
  • 4 × digital/analog open collector inputs/outputs

Additionally, using extension modules:

  • 4G (LTE) modem for two SIM cards in nano SIM format
  • Z-Wave and Zigbee
  • PoE 802.3af, 802.3at or Passive PoE
  • CAN and HDMI (in development, if needed, write to us)
Supported protocols

The basic controller supports a large number of protocols:

  • Modbus RTU - a wide range of devices: relays, dimmers, I / O modules
  • Somfy, WINDECO, DOOYA, AKKO, Dauerhaft, A-OK - electric curtains
  • IEC 61107, DLMS / COSEM electricity meters
  • 1-Wire - temperature sensors DS18B20
  • Wi-Fi, Bluetooth - sensors, gateways and devices
  • Modbus TCP, MQTT, SNMP, Zabbix API - data exchange with other controllers, servers and SCADA SCADA
  • Danfoss / Carel / Eliwell - refrigeration controllers

With add-on modules, you can add support for:

  • KNX - the controller can be integrated into existing KNX integrations
  • OpenTherm and eBUS - electric and gas boilers
  • Z-Wave, Zigbee - a wide range of sensors and actuators
  • DALI - two-wire lighting control protocol (in development)
Fast Modbus support

All Wiren Board devices, in addition to the standard Modbus RTU, can work with its extension Fast Modbus ⚡, which adds new features:

  • instant polling of input states and measured values via events;
  • quick search for devices connected to the controller;
  • resolving address collisions on the bus.

Additional features are enabled automatically - if the device supports extension, the controller driver will work with the device quickly Modbus if the device does not know anything about the extension - it will work using standard Modbus RTU.


Depending on the version, the controller can operate at air temperatures from -40 to +75 °C. It is often used in unheated outdoor panels.

Port overvoltage protection and a watchdog timer allow the controller to be used for solutions that require reliable operation.

The DIN rail housing and supply voltage range from 9 to 48 volts will help you integrate the controller into an existing automation panel or easily assemble a new one.

The open platform makes it possible to install third-party software or develop your own.

A wide range of external modules will help you build a fault-tolerant automation system for any task, and support for various data transfer protocols will help you integrate the controller into an existing one.

Quality control at every stage of production

We develop and manufacture all Wiren Board devices ourselves. Also everyone devices undergo multi-stage quality control:

  • During development - checking the components used for compliance with the declared ones characteristics and testing of the prototype device at extreme operating conditions.
  • After installation of SMD components - automated optical control.
  • After soldering the lead components - visual inspection of soldering.
  • After assembling the device, functional testing on an automated stand.
  • When shipped to the warehouse - control of completeness, stickers, appearance.

Thanks to this approach, the failure rate is no more than 0.5% of all released devices.

If the device fails within two years from the date of purchase, we we will replace it for free without need to be sent to a service center.



Quickly search for devices on the bus

Thanks to the support of Fast Modbus ⚡ in devices of Wiren Board and partners, you can instantly find all devices on the bus and add them to the configuration in one click drivers.

In the future we plan to add the ability to automatically resolve address collisions on bus and set the required connection settings.

Devices with regular Modbus and other protocols can be added to the configuration manually using templates with register descriptions. The standard driver package includes more than 150 templates and their number continues to grow.

Text dashboards

The main element of the text information panel is a widget. The widget allows you to display information from different sources in one place.

The text dashboard can adapt to the small screen of a mobile device.

Graphic dashboards

You can create interactive graphic dashboards based on SVG drawings.

You can output information to text elements of SVG-picture, change the visibility and design of elements. You can also customize the reaction to user action: turn on the light, turn off the alarm, etc.

To set up a graphical dashboard, the controller's web interface has a visual editor.

Data archive

All data received by the controller are saved in an archive, the size of which can be configured.

You can build graphs of historical data for several channels at the same time. You can interact with graphs: change the scale, make cursor measurements, etc.

Data from the archive can be uploaded to CSV for analysis in third-party software.

Automation scripts

The Wiren Board controller firmware contains a flexible scripting tool in Javascript-like language - WB-Rules.

Using scripts, you can automate any action: control lighting, heating or a technological process.

Scripts can be created and edited directly in the web interface, debugging is available in the console.
